To all whom t may concern."

Be it known that I, NELS P. JoRcENsoN, a citizen of the United States ofAmerica, and a resident of Waterloo, Blackhawk county, Iowa, haveinvented `certain new and useful Improvements in Conveyers, of which thefollowing is a specification.

My invention relates to improvements in conveyers, and the object of myimprovement is to furnish means for receiving, transporting anddelivering substances, such as barn or stable droppings, from thebuilding where Stich substances are iirst deposited to some place orreceptacle adapted to receive them.

This object I have accomplished by 'the mechanism which is hereinafterdescribed and claimed, and which is illustrated in the accompanyingdrawings, in which:

vFigure 1 is a side elevation of'my said conveying mechanism, as placedin a suitable position for use. Fig. 2 is an en larged detailcross-Section of thev kstable trough with the included scraping andconveying means, and of the means for actuating said conveying-means.Fig. 3 is a cross-section of one end of said trough, and of the mountsand other parts adjustable therein for supporting the end sprocketwheelof the conveyer-chain. Fig. 4'is a cross-section of the inner part ofthe foldable trough, and Fig. 5 is a cross-section of justablesupporting-means.

the outer part of the outer conveyer-trough, in each case thesupporting-meaus for the sprocket-chain idlers being shown. Fig. 6 is anenlarged elevation of one of the sprocket-idlers- Fig. 7 is a sideelevation of one of the end sprocket-idlers with its ad- Similarnumerals of reference denote corresponding parts throughout the severalviews.

Referring first to Figs. 1 and 2, the numeral 1 denotes .a concretetrough, which may be made in alined sections secured together ifdesired, adapted to be placed in a stable abutting upon the stalls in atrench suitably formed to receive it. The trough has depending spacedapart longitudinal parts 42 whose lower ends rest upon the top of thebottom of the trench so as to furnish an inclosed space between them inwhich the sprocket-chain 15 may travel. One part of this trough may-havea lateral projection 43 provided with a pit adapted to receive agear-wheel 42. The trough is of a rectangular form inl crosssection, andin 1t scraper-blades 16 of proper dimensions to extend across it toscrape over its bottom are located secured to the inner face of aconveyer-chainl. This chain being seated movably longitudinally throughthe middle of the trough 1passes about sprocket-idlers 27 and 26,located respectively at what will be called the rear end of theapparatus, and at the forward end of same. The chain has its dependingpart which travels in the space between the standards 42 of the trough1, further supported on idler-sprockets 36 and 17, which arerespectively supported in bearings in depending brackets 35 and 18respectively secured to the parts 20 and 21 of the movable trough of theapparatus: If deslred two such chains and an accordant system ofsupports may be adopted with connections to the scrapersblades 16, butthe method shown is simpler and cheaper, while retainin In or er to keepthe sprocket-chain 15 in a proper state of tension, I have adopted forthat purpose the following-descriloed means. Referring to Figs. 3 and 7,the numeral 46 denotes a metal plate mounted in the trough 1 at its rearend, securely, provided with a bearing for the vertical shaft the Sameprinciples of operation. y

29, and with a slideway 48 for a slide 47, the

wheel and said gears may be turned to adjust the position of said Slideaud of the idler' 27 to maintain the latter under proper tension.

. Any suitable mechanism may be employed to drive the chain 15forwardly, but I have shown means whichare now to be described. A frame5 is supportedon the forward'end of said concrete trough 1 and has atits upper end a bearing for a` short shaft 7 a crank 9 being removablyconnected to said shaft on one side of the frame and a bevel-pinion 3 isrotatably mounted having onits lefthand end a bevel-gear 42 in mesh withsaid pinion 41. Upon said shaft 3 is secured a relatively largesprocket-wheel 4. which meshes with said sprocket-chain 15. Vhen saidcrank 9 is rotated in one direction, said intervening mechanism causes aforward movement of said chain 15, carrying the vScrapers 16 forwardlythrough the trough 1 and-over the upper surface'of the communicatingtrough parts 20421. The troughparts 20 and 21 are preferably formed of 4large a number as may be useful.

metal, and the rear end of the part 20 is `hinged on pintles 33 to theuprights on the forward end of the concrete trough 1. The parts 2O and21 are hinged together by means of a hinge 19. In Fig. 1, the troughparts 20, 21 are showii extended forwardly in operative positions,` butsaid parts are made foldable to be retracted upon the wall of a buildingout of the way b v the following means. A cable 23 supports the outer orforward end off the trough' part 21., being secured to an eyebolt 24above in the building. Another cable 12 has one end fastened to a medialIpart of the trough 20 fis then passed upwardly over a. pulley in ablock 13', thence downwardly about a windi/n, ,drum

1.0 and thence downwardly again and about aV pulley 14 secured to the,base of the building and then secured to the trough 20. The cable 12 isdetachably secured to said drum 10 in the following manner. A smallcircula'r hollow or socket is formed in the middle Cil part of thecircumferential surface ofthe drum, and in said socket a circular bendof the cable 12 is placed, and then a screw 39 is passed down into thedrum through the hollow ol the cable-bend, its ianged head engaging thebend and securing it to the drum. In this Way, when the drum is turnedby means of its removable crank l1 in one direction, the upper part ofthe cable 12 is wound up while the other or lower part is slackened, andthe reverse occurs when the4 drum is reversely rotated. In this way, thetrough part 20 may be drawn up against the building, the part 21 foldingthereover.

'movable Since the scraper-blades 16 are located to face inwardly fromthe chain 15, it isnecessary to prov'de suitable sprocket-idlers topermit the b ades to pass them without interfering in transit. This iseffected by forming these wheels as shown in Figs. l andI 6, wherein'the webs between the sprocket-teeth lare reduced to but the rudiments2G, which are so near the axis that the scraper-blades 1G may fallbetween the teeth without interference.

The driving-sprocket wheel 4 has its teeth modified, as shown best inFig. 1, by having :their forward edges made straight and radial the rearedges only being curved, which causes the straight edges to pick up thei cham 15 and seize 1t with a secure grip un.

til released.

The trough section-s, whether ot' concrete or metal may be formed 1nahned parts of as Having described my invention, what I c laim as new,and desire to secure by Letters Patent, is:

-1. 1n a conveyor, a horizontal fixed integral body longitudinallytroughed at top and bottom, a movable endless chain passed about saidbody within both troughs and spaced apart therefrom,y scraper-bladesfitting the interior of the upper trough and therethrough longitudinallyto scrape its bottom and adapted to return through said lowertr'ough,said blades being secured ixedly to links of said chain on their innerfaces.

2'. In a conveyer, a fixed body provided on its upper face withupstanding fixed integral spaced apart walls to provide an open-endedlongitudinal trough therebetween, and having integral depending spacedapart walls to provide a down wardly-opening openlended trough on itsunder side opposite the upper most trough, an endless movable chainpassed about said boetvwithin said troughs and spaced apart'thcrefrommedially, -and scraper-blades secured to inner faces of links ci' saidchain and depending toward the bottom of the upper trough and adapted tofit the trough and scrape over its bottom and to return within thelowertrough.
